LOS ANGELES (AP) — The Los Angeles Police Department said its detectives have apologized to the family of Notorious B.I.G. for failing to warn them that it planned to release his long-sealed autopsy report.

The Los Angeles Times reports detectives released the 15-year-old report last week in hopes of getting new tips in the unsolved murder. The report revealed that injuries cause by a single bullet killed the rapper during a drive-by shooting in March 1997.
